Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gear quenching, in particular to a component used for gear quenching. Background Art
[0002] In the gear production workshop, in order to improve the strength, hardness, wear resistance and fatigue limit of the gear surface layer, it is necessary to quench the surface of the gear to strengthen the surface of the gear. The existing gear quenching uses electromagnetic induction heating, and then puts the gear in the coolant to cool down. After the existing gear quenching device has processed multiple gears, the temperature of the coolant will increase, thereby reducing the cooling rate of the coolant, resulting in the quenching treatment of the gear not meeting the requirements, and the coolant is often discharged directly after use, which is not fully utilized and wastes water resources. When the gear is quenched, the surface temperature of the gear is very high, and it will also emit heat radiation to the outside world, which will deteriorate the surrounding environment and affect the workers' status. For this reason, we propose a component for gear quenching. Utility Model Content
